Answer:
6.21 rad/s
1.3041 m/s, 0.567 m/s²
Explanation:
= Final angular velocity
= Initial angular velocity = 0
= Angular acceleration = 2.3 rad/s²
= Angle of rotation
t = Time taken = 2.3 s
Equation of rotational motion
The angular speed is 6.21 rad/s
Linear velocity is given by
Linear velocity is 1.3041 m/s
Tangential acceleration is given by
Tangential acceleration is 0.567 m/s²
In degress the angle would be
From x axis it would be
The angle is from x axis
Answer:
A conductor allows free charges to move about within it. The electrical forces around a conductor will cause free charges to move around inside the conductor until static equilibrium is reached. Any excess charge will collect along the surface of a conductor. Conductors with sharp corners or points will collect more charge at those points.
Explanation:
Answer:
A battery produces _DC_ current, which is current that flows in only one direction.

Explanation:I just got it right:)
Best Answer:<span> </span><span>The net angle between the direction of flight of the aircraft and the wind in the opposing direction is 20. THe component opposing the aircraft is 2.4*cos 20 KN
= 2400 * 0.9397 = 2255.2622 N. The distance covered is 120 Km
The work done by the aircraft overcoming the wind is
= 2255.2622 * 120000 = 270631464 = 2.71 x 10^8 N
As the question is trickily worded as : the work done on the plane by the air (wind) the answer is -2.71 x 10^8 J . (fourth option)</span>
